Research Project: Design of thermoformable composites for additive manufacturing: mechanical performance optimization and study of end-of-life strategies
After completing my Master's degree from the Material Science & Engineering department at UW, I now continue my research as a Ph.D student. I am working with Prof. Roumeli, in collaboration with Prof. Dwayne Arola, to manufacture thermoformable composite structures. This work, along with further mechanical and thermal characterization, will focus on the creation of strong and reliable hierarchical composites for additive manufacturing. Additional work will explore the end-of-life recyclability, degradation, or pyrolysis to entice usage of these more sustainable materials. I am passionate about 3D printing and love designing trinkets for my hobbies: skiing, biking, and sailing!

Research Project: Processing and development of self-plasiticizing biocomposites using natural materials as a matrix
I graduated from the Georgia Institute of Technology with a degree in Materials Science and Engineering in Dec, 2020. At Georgia Tech, I studied the processing of polymer composites by way of electrospinning and direct ink writing under the advisement of Dr. Blair Brettmann. Since beginning my PhD in material science in the fall of 2021, I have applied my knowledge of polymer science to begin the development of a physical analogue for biomatter plastics. I hope to combine these efforts with the extraction of macromolecules from biomatter to identify mechanisms governing self-boning in algal bioplastics.

Research Project: Biomass-laden cement biocomposites as sustainable structural materials
I obtained my Master's degree in civil engineering with a focus on structural materials at the National Cheng Kung University (Taiwan). My previous research focused on the elastoplastic behavior of foam and reuse of industrial byproducts as constructional materials. I am currently investigating the interaction between biomass (e.g., algae cells) with cements and its structure-properties relationships.

Research Project: Plasticization of biomass through mechanical and thermal treatments
I got my Master's from the department of Materials Science and Engineering at the UW. Previously, I received my B.S. in Mechanical Engineering at Purdue University in 2017. In-between I was working with composites in the aerospace industry. My goal is to use my mechanical background to facilitate the development and characterization of bio-based polymers and explore machine learning tools to assist us in the more efficient design of sustainable materials.

Research Project: Bacterial cellulose for medical applications
I obtained my B.S in Chemical Engineering and my M.S. in Materials Science and Engineering at the Federal University of Pernambuco (Recife, Brazil). For my PhD, I got awarded the CAPES-Print Fellowship (Brazil) to conduct my research at the University of Washington as a visiting scholar. My research focuses on bacterial cellulose production and processing through in-situ and ex-situ methods with the aim to create sustainable and functional materials to be applied in the biomedical field.

Research Project: Zeolite-cement composite systems for sustainable structural materials
I have received both my B.S. and M.S. in Materials Science and Engineering from the University of Washington. Having previously conducted research on algal biomass-cement composites, I am now studying zeolite as a partial replacement for cement in concrete composite systems with collaborative guidance and supervision from
Dr. Roumeli and Dr. Arola. Outside of my research in structural materials, I am the co-founder of a medical device startup with the aim of improving gastrointestinal surgeries.

Research Project: Effect of processing on bacterial cellulose products
I completed my Bachelor of Engineering in Metallurgical and Material Engineering from Jadavpur University, where I conducted research on the synthesis of mixed metal oxide-graphene composites for heavy metal removal, which could be applied in water purification. Currently, I am focusing on developing models that can correlate the colloidal behavior of cellulose dispersions to the mechanical properties of films and foams obtained from them. Through my work, I hope to contribute to the development of eco-friendly solutions for various industries, while also promoting the use of sustainable materials in structural applications.

Research Project: Development and processing of BCNPs for surface functionalization, drug incorporation and release, and biocompatibility studies
I completed my B.S. in Chemistry at the University of California San Diego in March 2021 where I researched silicon nanotechnology for diagnostic applications. In Fall 2021, I started in the Molecular Engineering PhD program at UW, and I initiated an interdisciplinary collaboration between Dr. Roumeli’s sustainable biomaterials lab and Dr. Nance’s disease-directed engineering lab. My co-advise position provides me with the opportunity to engineer bacterial cellulose nanoparticles as a novel and sustainably-sourced and formulated drug delivery system to treat neonatal brain injury. I am passionate about sustainable nanotherapeutics using green engineering and exploring the great outdoors in WA.
